Background technology
National theater is city-level emphasis cultural center, Ordos City, and regional joint performance center, provincialism cultural industry base are one of the 11 Asian culture art festival playgrounds.Be main body, the outstanding mental attitude that embodies Erdos opening, innovation, scientific development for representing the abundant minority people in Inner Mongolia Autonomous Region, the Ordos City culture of travelling.This engineering outward appearance is two round hats, and the prototype of its design concept is respectively from Inner Mongol men and women's national cap.Moulded is the steel circle cap cylinder that two rectangular tube oblique braidings of turning round with arc form, and forms construction area 37800m by great circle (theater), roundlet (music hall) and three parts of intermediate connector
2Because spatial curved surface spiral box type component is made construction technology and can be sought beyond example, my company's self-developing goes out a kind of spatial curved surface spiral box type component preparation method, started the beginning that spatial curved surface spiral box type component is made, economic benefit is obvious in processing the special-shaped steel structure Components Composition, improve the technical merit of steel construction industry, promoted the development of steel construction industry.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of spatial curved surface spiral box type component.The method can be various space curved surface spiral polygon steel Mechanical Builds the technological guidance is provided.
The technical solution adopted in the present invention is:
1, adopts the modeling software XSTEEL software of setting up physical model and the CAD mapping software of mapping software of drawing detail of construction, in conjunction with setting up the stereoeffect model, extract the three dimensional space coordinate (X of single-piece spatial curved surface spiral box type component according to structural model, Y, Z), provide the assembled mold figure of single rod member;
2, spatial model is imported mapping software, adopt approximate principle, every the member spatial model that takes out is carried out described point, the recycling mapping software obtains each face steel plate cutting detail drawing of box-type member with the model expansion setting-out.
3, according to the assembled mold figure of single rod member, utilize the accurate measurement instrument such as total powerstation to set up Special mould according to three-dimensional coordinate, this mold radian box-type member consistent with the box-type member radian and only applicable this radian is made.
4, numerical control cutting machine is adopted in the blanking of box-type member wallboard, utilizes veneer reeling machine to press arc after the steel plate cutting.
5, single-piece member is assembled at Special mould, guarantee that carrying out backing welding after control point on each plate and the mold coincide connects, then carry out the submerged arc capping at the planer-type submerged arc welding machine, after welding is finished box-type member is reapposed on the former Special mould and detects, guarantee member appearance and size, then carry out the pre-assembly unit of integral body.
6, carry out pre-assembly unit according to installation unit, guarantee that member integrated connects precision.
Adopt approximate principle, every the member spatial model that takes out is carried out described point, be combined with XSTEEL software and CAD software, the spatially spiral member is changed into the plane detail of construction.
The invention has the beneficial effects as follows, realized the making of spatial curved surface spiral box type component, process that spacial special-shaped steel structure member is made, successful in the assembling, improved the technical merit of steel construction industry, promoted the development of steel construction industry.

The specific embodiment
The specific embodiment of the present invention adopts the following steps construction:
1, modeling and definite rod member mold locus coordinate
According to a design drawing, utilize CAD software to carry out space three-dimensional linear modelling (Fig. 1).CAD Linear data importing X-STEEL software is carried out spatial entities modeling (Fig. 2).Extract the three dimensional space coordinate (X, Y, Z) of single-piece spatial curved surface spiral box type component according to physical model, provide the assembled mold coordinate points of single rod member.
2, blanking detail drawing in-depth
Spatial model is imported to (Fig. 3) among the CAD of mapping software again from X-STEEL software, realize the physical model among the XSTEEL is transformed among the CAD.The single-piece member spatial model (Fig. 4) that takes out is carried out described point, respectively the drawn multi-section-line of each face described point is carried out space projection, by expansion setting-out, obtain each face steel plate cutting detail drawing of box-type member.The girder steel blanking is arc, marks rise every 1m in the blanking detail drawing, so that the dimensional gaughing after the blanking.
3, Special mould is set up
Because the space coordinates of every box-type member is not identical, every rod member all need be set up Special mould.Mold utilizes the materials such as cut deal, I-steel to set up on solid ground.The mold control point adopts spirit level, theodolite and total powerstation to measure control, guarantees that mold control point coordinate is consistent with model space three-dimensional coordinate.
4, blanking
Numerical control cutting machine is adopted in the blanking of box-type member wallboard, in the blanking detail drawing CAD program input numerical control cutting machine control program that launches, automatically carries out steel plate cutting.According to the camber line rise of drawing sign, check blank size after the blanking.After the steel plate cutting size is errorless, utilize veneer reeling machine to press arc according to the radian of spatial model, guarantee that steel plate radian and mold radian match.
5, assembly welding
Single-piece member is assembled at Special mould, guarantees during assembling that the control point on each plate and the mold coincide.Assembling flow path is tire on the base plate → assembling dividing plate, technique dividing plate → assembling two coxostermum → welding → lid top panel.During assembling, adjust base plate position and fixing according to the control point on the mold.Elder generation's packaging technology dividing plate is assembled two coxostermums again and is become U-shaped.Carry out the welding of interior wing curtain after the U-shaped moulding, carry out at last the lid top panel package size and carry out backing welding after qualified and connect, then carry out the submerged arc capping at the planer-type submerged arc welding machine.Welding is finished the laggard box-type member of being about to and is reapposed on the former Special mould and checks, checks whether the Position Control on the member overlaps with the mold control point, should the correcting of position deviation.
6, pre-assembly unit
After single-piece member completes, carry out the pre-assembly unit of integral body according to installation unit.Set up whole mold during assembly unit, check the docking port size, check the qualified rear welded and installed location-plate of size.
